Removed the rear 02 reading with my ITSX, doesnt work.
tried adding fuel at WOT by 4%, still popping back.
what else?

An air intake, leak
Vacuum leak
or Exhaust leak are more likely the culprits.
Aftermarket Cold air kits need varying degrees of calibration to keep fuel trims in check.
This code will not set at WOT it sets in closed loop when fuel trims exceed 12%
